IMPROVEMENT IN NETTIN'G-MACHINES.

Specification forming-part of Letters Patent No. 152,062, dated J une16, 1874; application iiled December 10, 1873.

To all whom 'it may concern:

Be it known that I, BENJAMIN ARNOLD, of East Greenwich, in the county ofKent and State of Rhode Island, have invented certain 'Improvements inMachines for Making Net- 'each other by means of grooves in the front,

back, and bottom of the support that holds them combined withknot-forming mechanism,

`as hereinafter described; and, also, in a series of hooks correspondingin number with the flat stationary bobbins combined with the latter, andso moved and guided as to convey a loop of twine from a separate set ofbobbins over each lia-t bobbin, and leave it on the under side, so thatwhen the loops are dra-w11 up they shall have passed around the bobbins;also, in combining two bars, one having a row of pins in its edgecorresponding in space with the flat bobbins, and the other having onits Vedge a row of longer pins with holes or eyes -m thelr endscorresponding in space with the pins in the first bar, to form loops ofthe twine from the large bobbins; also, iu two rolls geared together andplaced near eac-h other, with a bar or loose roll placed on top so as torest on bothof them, combined with certain mechanism, as hereinafterdescribed, for operating them to feed the net or twine through themachine; also, in a roll with staples set in its surface, through whichthe twines from the large bobbins pass, in combination with guides soplaced as to cause the twines to wind up on themselves, and draw up theloops and knots when the roll is turned; also, in a guide-platemade'withvertical slots, and placed between the bars with pins, and the flatbobbins to guide the twines from the large bobbins and draw olf slackfrom the flat bobbins; also, in a series of points to open the loopsthat are formed by the pins before mentioned, and drawn out by thehooks, as herein described; and, further, in certain devices to give theproper motions to the above-men- Y tioned parts.

Fig. 2 is a vertical cross-section indirection ofthe dotted line a a in Fig. 1, looking to the left hand.Fig. 3 is a vertical cross-section in direction of the dotted line b bin Fig. 1, looking to the right hand. Fig. 4 is a verticalcross-section, taken in direction of the line c c in Fig. l, looking tothe left hand. Fig. 5 is an elevation of the right end of Fig. l. Fig. 6shows a perspective view of the machine. Fig: 7 is an elevation of theupper part of the lefthand end of Fig. l, with the driving-pulleyremoved. Fig. 8 is a back view of a part of the trough, showing thedevices for opening the loops on the hooks. Fig. 9 shows the arrangementof the knee-levers that hold and move the two pin-bars, O K. Fig. 10shows how the guide-bar holds the twine, so that it shall bind on thetie-roll. Figs. ll'to 17 inclusive show the positions of the twopin-bars O K, the twine, and the hooks in making the knots7 A A are twoend frames, connected together by beams C C 0 at the front, back, andbottom. B is the main shaft, turning in bearings in each end frame. Onthis shaft are secured the cam O near the left end, and the cani D withgear-wheel E at the right end, and a loose sleeve, J, extends on theshaft nearly the whole distance between the two cams. To this sleeve thearms m are fastened. The cam C moves in succession the three levers a bc, and the lever a operates the sleeve J by means of the connecting-bard attached to an arm on the sleeve. The lever b turns the tieroll F bymeans of the segment-gear on its upper en d, and the gear-wheel c on thetie-roll. This lever is brought back against the cam by the weight i, orin some other suitable way.

The lever c operates the feed-rolls G H by means of the connecting-rodg, lever j, rod k, geanrack h, and gear-wheel l', which is fast on asleeve, to the outer end of which the arm k is fastened, which drivesthe ratchetwheel I, fastened to the back feed-roll, by means of pawlsonthe outer end of the arm I, (see Fig. 1,) the sleeve, &c., in section.Gam D (see Figs. 3 and 9) moves, by the outer groove on its inner side,the lever Z, which pushes the pin-bar K back and forward by the connecting-rod a, knee-lever o, bar p, and knee-levers t. By the inner grooveon the same face, it

moves the lever S, which raises land lowers the guide-plate j' by meansof the rod q, kneelever r, and bar m. (See Fig. 9.) The cam l), by thegroove in iis outer side, (see Figs.

5 and 9,) moves the kver N, which raises and y lowers the pin-bar O bythe connecting-rod c,

or to every row of knots made; and the cam h attached to this gear-wheellj gives those motions that are required to be the reverse inV tying onerow of knots to what they were in the row next previous. The groove onthe inside of the ea-m Q (see Figs. 3 and 9) moves the lever R, whichmoves the eye-bar O endwise by means of the connecting-bar y, kneeleveror rocker-shaft z z, and bar c'. The shape of one-half of each groove onboth sides of this cam is the reverse of the other Vhalf of the samegroove, for the purpose of tying the knots right and left, to make themeshes diagonal. rllhe groove in the outside of the cam Q., Fig. 5,moves the lever Swhich gives motion endwise to the pin-bar K by the rody', knee-lever x', Fig. 3, and the connecting-bar 'Lc'. The arms m' onthe sleeve J (see Fig. 4) are connected to the bar V by the rods 'u'. In

this bar V a row of curved hooks, t', are set,.

agreeing in number and location with the at bobbins s', for the purposeof drawing the loops over the bobbins. The bar V (see Fig. 4) is guidedin curved ways U by the arm W, which has a friction-roll near its lowerend ruiming in the groove M. These oblige the hooks to catch the loops,draw them over the bobbins s', and cast themoif below. X is a trough,supported at each end over the front of the roll Gr, to hold the extrabobbins to replenish the machine with, and also to support the devicesfor opening the loops as they pass over the bobbins s'. These devicesconsist of the knee-levers g', (see Figs. 7 and 8,) pivoted to the backof the trough, and connected by the strips 0' to the bar p', which ismade with a row of V-shaped points agreeing in number with the hooks t'.The other ends of the knee-levers q' are pivoted to the bar Y, which isoperated by means of the knee-lever fi', connecting-rod h', and lever z,which is moved by a pin, d', in the wheel B'. The points on the bar p'spread the sides of the loops apart, so as to enable them to pass downcach side of the bobbins s'. The large bobbins n' hold the twine ofwhich the loops are made that are passed over the bobbins s'. The leverD (see Fig. 7) is pivoted at one end to the frame A,

and connected at the other end tothe arm k' by the rod 1"'. It is pusheddown by the pin d' in the wheel B', when the tie-roll has taken up mostof the slack of the knot, to cause the feed-rolls to draw the row ofknots that are being made away from the eyes a little, so

that they may be `properly drawn up tight without being drawn into theeyes. The-guideplatej' is placed on knee-levers, or their equivalents,sothat it may be raised for the purpose of drawing off slack twine fromthe flat bobbins, to form a part of the knot; and it is furnished withslots to receive the twines from the'large bobbins, so as tov guide themwithout drawing on themwhen the plate is raised to get slack from thefiat bobbins. The plate is operated by the lever S, rod q, knee-lever r,and bar m, and the inner grooves on cam-plate D. (See Fig. 9.) The twinea' is threaded in, as shown in Fig. 4-that is, from the large bobbins u'back over the bar b'; then up to the guides on the front of the bar H',thence through the staples in the tie-roll F, and ,through the guides onthe top of bar H', then through theV guid-e-platej' and the eyes in thebar O to the bottom of frontfeed-roll; then up between the rolls, overthe bar c', on top and down between the rolls, and out under the backfeed-roll. rlhe iiat bobbins s' are placed on a support, (see Fig. 4,)and held separate from each other by ridges, forming grooves in thefront, bottom, and back of the support, in which the bobbins Vstand ontheir edges. The twine c' from these bobbins'goes up through thefeed-rolls in the same manner as the twine from the large bobbins, orthey may be tied to the twines a' in front of feedrollG The machine'isdriven by means of a belt on the pulley B', which is fast on the mainshaft. The knots are formed as follows The pin-bar K comes forward andthe eye-bar O drops down, (see Fig. 11,) then the pin-bar moves sidewiseandthe eye-bar rises a little, (see Fig. 12,) then the pin-bar drawsback far enoughA for the pins to clear the eyes and moves sidewise andforward to its iirst position, and the eye-bar drops down. (See Fig.13.) The pin-bar now comes forward over the eyes and a little sidewise,so that when the eyes rise a little they are back of the lower part ofthe twine around the pins, (sec Fig. 14;) then as the pin-bar movesback, the eyes rise inside tlieloop around the pins, (see Fig. 15,) andthe hooks t' enter 'under that portion of the twine that extends fromthe eye to the pin farthest from it, and catch it, the eyes droppingdown a little to draw the twine onto the hooks, which then draw back andcarry the loops which are opened by the points in bar p' down over theiiat bobbins, casting them oil' at the bottom by passing under the ledgeon which the bobbins stand. The tie-roll F now begins -to turn and drawsthe loopsup back of the bobbins s' .and around the twine c', as seen inFig. 16, the pinbar meantime having 'drawn back and left the twinesaround the eyes. Then the eye-pins drop out of the knot and it is drawnup tight (see Fig. 17) by a further turn of the tie-roll.

The large bobbin-twines tie rows of knots alternately with the flatbobbins to the right of them, and with those on their left. This isaccomplished by reversing the endwise motions of the 1two pilrbais linthe .alternate rows, the

othermotions remain-ingthe same. This makes the meshes diagonal to thesides of the netting.

` At this time the cam C has moved around, so

as to press on thelever c, Fig. 2, and turn the feedrolls G H by theconnecting-bars and levers, as before described, so as to draw the rowof'knot's just made back from the pins, the distance they are drawn backbeing the size of the mesh, and it is regulated by sliding the clamp gon the lever j toward its pivot, so as to lessen the amount of drawmotion on the rack h to lessen the size of the mesh, and the clamp isslid toward the outer end of the lever to increase the motion of thefeed-rack and make the meshes larger. The arrangement of the guides onthe bar H', whereby the twine is allowed to draw freely through thestaple in the tie-roll F, when that roll is turned in to its farthestpoint and the loop is being made, and the way that one part of the twinebinds on another portion when the roll turns out, so as to both draw upthe loop and knot, and at the same time draw oi the necessary amount oftwine from the large bobbins for thenext mesh, are shown in Fig. 10.

In Fig. 3 is shown the manner of gearing the feed-rolls G H, so that theback one, which is driven by the rack h, shall turn the front one.

The rod u', Fig. 2, connects the lever a to the lever c through thelever j, so that when either one is operating it will draw the otherback to the cam. At s, Fig. 4, a small rod or wire may be laid on thetwine between the roll F and bar H to make friction on the twines, andanother rod may be put on the twines between the roll F and the bar b totake up the slack l twine when the roll turns back to place.
